restore window configuration after org-edit-src-exit

[Richard Kim]

About a year ago change 819e98afd018cad3c13fd58bfcbd979ab36dfbc7 was checked in to remove code that restored window configuration when org-edit-src-exit finished. The net result is af if C-x 1 is called to remove all windows except the org buffer just edited. This is very inconvenient.

Why not call winner-undo to restore window configuration as shown here?

For now I'm using the following advice do the same thing.

(defadvice org-edit-src-exit (after restore-window-config activate)
  (winner-undo))
